How models are selected
Flagship and reasoning models, sorted by context window size then blended cost.
Prices are per million tokens (Mtok), sourced directly from official provider pricing pages and verified by our automated scraper pipeline that runs 3x daily. "Blended cost" is the average of input and output pricing — a quick proxy for typical 50/50 usage patterns.
